i find this :

http://www.mathworks.com/access/helpdesk/help/toolbox/mupad/plot/PRIMITIV_Implicit2d.html

but i try the example:
plot(plot::Implicit2d(x^2+y^2-1, x = -1..1, y = -1..1))

and matlab find an error..
>> plot(plot::Implicit2d(x^2+y^2-1, x = -1..1, y = -1..1))
??? plot(plot::Implicit2d(x^2+y^2-1, x = -1..1, y = -1..1))
|
Error: Unexpected MATLAB operator.

how can i resolve?
thanks
